Structure diagram and installation diagram of emergency shut-off valve
Shanghai Yonglong Valve Factory collates a structural diagram of emergency shut-off valve and an installation diagram of emergency shut-off valve for everyone to understand the details of internal structural parts of pneumatic shut-off valve, wiring method and common sense of correct installation method.
● Structural dimension drawing of emergency shut-off valve: The shut-off valve is composed of valve body, valve disc, valve stem, sealing ring, strong spring, piston cylinder, fusible alloy plug, waterproof glass cover, bolt fastener, metal graphite gasket and connecting rod. It can be equipped with solenoid valve coil, air filter pressure reducing valve, and annunciator (manual device can be loaded) to form an automatic control fluid valve. It is used as the valve of emergency switch in storage tank, ammonia station and liquefied gas filling station.
● Emergency shut-off valve Wiring diagram: Connect with the gas alarm, detect the density of the medium in the air through the gas leakage probe, give the host a signal alarm, cut off the power supply of the host to exhaust the air source pressure, and close the valve for pressure relief.
● Installation diagram of emergency shut-off valve: The inlet pipe installed on the storage tank is connected to the liquid ammonia stop valve and the liquid ammonia check valve in the front. The liquid ammonia stop valve is kept in the normally open state. The check valve prevents the reverse flow of the medium. If the medium is in the same input and output pipeline, the check valve cannot be installed.
● Schematic diagram of emergency shut-off valve connection: Manual Ammonia stop valve It is usually kept in the normally open state, which is used to prevent the shut-off valve from being damaged or the manual valve that is closed after replacement and maintenance. The other end is connected to the metal hose, quick coupling and manual valve.
●“ YongLong valve ： We have been learning from Germany, Japan and South Korea in their pursuit of high quality standards, actively innovating and expanding the domestic and foreign market- "We are not the best, but we try to do better!"
